1) [8 points] You've been hired by Map Masters to write a C++ console application that calculates and displays the distance between two points on a map. Prompt the user for four integer coordinates:

x1

y1

x2

y2

Calculate the distance in kilometers from (x1, y1) to (x2, y2). See www.mathsisfun.com/algebra/distance-2-points.html for background information. Use function sqrt() to calculate the square root of . Use formatted output manipulators (setw, left/right) to print the following five rows:

x1

y1

x2

y2

Distance

And three columns:

A left-justified label.

A right-justified value.

A left-justified units (output manipulators not needed here, just place one space before the units name to separate it from the second column).

Define constants for the column widths. Format all real numbers to one decimal place.
